“Sweet peas are a popular choice to sow in pots indoors, and they have a wonderful scent and provide bright splashes of colour from early summer,” says Julian.

Perfect for picking, sweet peas can be easily grown from seed in small pots (you can also use a cardboard toilet roll as a container). When the plants grow to 10cm tall, ‘pinch’ out the tips to encourage more growth. Plant them in mid-spring along a trellis or wall for beautiful, climbing displays.

According to Julian, hardy annuals like pansies, violas and calendulas also do well if sown indoors for early colour next spring. Sowing them in the autumn encourages stronger root growth, leading to more prolific flowering.

Organised gardeners can also get ahead by planting the seeds of beautiful flowers, including globe thistles (echinops), cornflowers, rudbeckia, delphiniums, scabiosa and foxgloves. Sow in a compost tray before moving outside when the weather warms in spring.
